Nomad to mixamo black void texture problem?

Hello! I am experimenting with mixamo, importing a character that has been UV unwrapped and normal/texture baked from a high poly version. But the character is coming out black in mixamo. I am not sure if this is a problem with mixamo or some sort of file error from nomad? Does anyone have any experience with using files from nomad imported to mixamo? A googled search came up empty. Would love to resolve the issue. It says online that mixamo should render textures just fine, and they do have textured characters on there already.

ok, I tried to export the model anyway and it seems to be fine once exported. so it is just a problem in the Mixamo viewer.
